swing to a normally closedposition.

An object of this invention is to" provide a door structure of this kind which can be easily and quickly, mountedjjin a door openinggthe 'device including a; pair of door members which are hingedlyf'secured together and also hingedly secured to the doorframe structure.

Another object of this invention is to provide in adoor structure of this kind, a pair of swing door members'which are hingedly connected together and which includes means whereby one of the doormembers is limited in its swinging movement relative to the other door member.

' A further object of this invention is to provide a novel means for swingably suspending one door member from, another and also swingably suspending the other door member within a door frame. e p

e A still further object of this invention is to provide a door mounting means which is adapted to besecured toa pair of door members, the mount- [ing meansbeing. relatively simple in constructionjso that it'will .not readily" get out of order under rough usage. p e l Totheforegoing objects and to others which mayhereinafter appear, the invention consists of the,noyellconstruction, combination and arrange-' ment of parts as will be more specifically referred to and illustrated in the accompanying drawing wherein are shown embodiments of the invention, but it is to be understood that changes, variations and modifications maybe resorted to which fall within the scope of the invention as claimed.

Figure 1 is a detail front elevation of a door structure embodying this invention which, is

swingably mountedih a door frame.

Figure 2 is'a sectional view taken on the line 22 of Figure .1. I

. view taken on the line -5 of Figure 1. 1

Referring to the drawing, the numeral III designates generally a door frame structure including apair of sideframe members II, an upper rail or horizontal frame bar l2 and a sill I3.

An upper door member I4 is disposed between the two side members I I closely adjacent the rail or upper frame member I2 and is swingably disposed between the side members II by a mounting means which includes a pair of vertically disposed channel members I5. The channel mem bers I5 areof U-shaped or L-shaped configuration and an attaching plate I6 is welded adjacent its outer edge to one side ll of the channel mern- The plate I6 is secured to one face of the upper door member I4 by fastening devices I8 which may be in the form of rivets, bolts or the like.

The upper end portion of each channel member V I5 is swingably secured to a vertical frame member I I by means of apivot I 9 in the form of a lag screw or the like which extends through the bight 20 of the channel member I5. The channel member I5 extends downwardly from the upper door member I4 and engages in a cut-out portion 2 I which is cut out from a lower door member 22. r I

An L-shaped strip 23 has one side 24 thereof secured as by fastening devices 25 to one face of the lower door member 22 and the other legZIi of the L-shaped member 23 is provided with an opening 2'I through which a headed pivotmember 28 engages. The bight 20 of the channel member I5 is provided with a plurality of spaced apart openings 29 which extend upwardly from [the lower end thereof and the pintle or pivot member 28 is adapted to engage through a'se lected'one of the openings 29. A cotter pin 30 is extended transversely through the pintle or pin 28 and engages within the channel formed between the two' sides I1 and 3| of the channel member l5. 7 v

The leg 26 of the L-shaped member 23 extends outwardly of the opposite side or face of thedoor 22 to which the supporting member 23 is secured .extendingthrough a recess or slot 32 which is formed in an edge of the lower door memberZZ. The terminal end of the leg 26 is provided with a right angularly disposed stop member 33 which is adapted to engage the channel member when the lower door member 22 is rocked upwardly from its lower end in one direction so as to thereby limit the swinging movement of the lower door member 22 relative to the swinging channel members I5.

In the use and operation of this double-action door structure, the channel members swingably secured between the side members II of the door frame structure II] by securing the lag bolts I9 in the frame members II. The upper )fumrso STATES PATENT OFFICE 1..

I5 are.

pivot members l9 are disposed above the center of the upper door member I4 and in like manner the pintles or pivot members 28 are mounted in a position above the center of the lower door member 22 so that these two door members will gravitatingly swing back to a vertical position. Preferably the lower door member 22 is substantially longer than the upper door member l4 so that when the small animals desire to go one way or the other through the door opening formed by the frame II], the animals may push the lower portion of the lower door member 22 thereby swinging this lower door member on the pintles or pivot members 28.

In the event the animals are not able to pass through the door opening formed by the lower door member 22, additional pressure on the lower door member 22 will cause the stop member 33 to engage the channel member l5 above the pintle 28 and effect an outward swinging of the channel members I5 together with an outward swinging of the upper door member M.

A door structure and mounting means con structed according to this invention may be manufactured at a relatively small cost and the component parts of the mounting means are so constructed that they can withstand considerable hard usage before getting out of order.

Furthermore, by providing a double-acting door structure and a mounting means therefor as hereinbefore described, the door frame structure may have the opening thereof maintained in a normally closed position but animals may easily and quickly pass through the door opening by pushing against the lower door so as to effect a swinging of this door in addition to a swinging of the upper door M where the lower door 22 will not provide sufficient opening for the animals to pass through the door frame opening.

What I claim is:

1. A double-acting door structure and mounting means therefor comprising an upper door member, a lower door member, a pair of depending suspension members disposed at the opposite vertical edges of said door members, means fixedly securing the upper portions of said suspension members to said upper door member, pivot means engaging the upper portions of said suspension members pivotally supporting said suspension members, means pivotally securing said lower door member to the lower portions of said suspension members, and means carried by said lower door engageable with said suspension members to limit the swinging movement of said lower door in one direction.

2. A double-acting door structure and mounting means therefor comprising an upper door member, a lower door member, a pair of elongated suspension members U-shaped in transverse section, a plate fixed to one side of a suspension member, means securing said plates to said upper door member, means pivotally supporting said suspension members, a pair of L- shaped members, means engaging one side of said L-shaped members securing said latter members to said lower door, said suspension members having a plurality of spaced openings in the bights thereof, and a pintle engaging through the other side of an L-shaped member and in a selected opening of suspension member pivotally securing said lower door member to said suspension members.
